80CNQ035SL

Overview

The 80CNQ035SL is a Schottky diode array manufactured by SMC Diode Solutions, featuring a dual common cathode configuration. It provides a maximum repetitive reverse voltage of 35 V and an average rectified forward current of 40 A per diode. The component utilizes the PRM2-SL surface mount package. Key electrical characteristics include a forward voltage of 740 mV at 80 A and a reverse leakage current of 5 mA at 35 V. It operates within a junction temperature range of -55°C to 175°C.

Feature Summary

• Schottky barrier technology for low forward voltage drop
• Dual common cathode configuration in a single module
• Surface mount PRM2-SL package design
• High thermal stability with extended junction temperature range

Applications

• DC-DC converter output rectification
• Free-wheeling diodes in power supplies
• Low voltage high current rectification circuits
• Solar panel bypass applications

Procurement Notes

Verify the specific suffix SL against the official datasheet to confirm the PRM2-SL surface mount package variant. Ensure that the required current rating aligns with the 40 A specification per diode under your thermal management conditions. Confirm RoHS3 compliance status if environmental regulations apply to your assembly process. Cross-reference the manufacturer part number directly with SMC Diode Solutions documentation to avoid substitution errors.

Selection Notes

Select this component when a low forward voltage drop is critical for efficiency in 35 V systems. The dual common cathode arrangement simplifies circuit layout compared to discrete solutions. Evaluate the thermal resistance of the PRM2-SL package to ensure adequate heat dissipation for continuous 40 A operation. Consider the 175°C junction temperature capability for high-temperature environments.

Part Context

This device belongs to the CNQ series of Schottky diode arrays from SMC Diode Solutions. The series offers various voltage and current ratings packaged in standard industrial footprints. The 80CNQ035SL specifically targets applications requiring robust performance at moderate voltages with high current capacity in a compact surface mount form factor.

Replacement Considerations

Direct replacements must match the 35 V reverse voltage, 40 A current rating, and PRM2-SL package dimensions. Verify pinout compatibility for common cathode configurations. Check forward voltage and leakage specifications to ensure equivalent or better performance in the target application.
